4. Asagid aki işlemlerden hangisinin sonucu en bũ- yüktür? A) (9)/(2)cdot (9)/(2) C) 3(1)/(5)cdot (6)/(5) B) 3 (3)/(5) D) 9.(1)/(5)

Let's calculate each option to determine which one has the largest result:<br /><br />A) \(\frac{9}{2} \cdot \frac{9}{2} = \frac{81}{4} = 20.25\)<br /><br />B) \(3 \cdot \frac{3}{5} = \frac{9}{5} = 1.8\)<br /><br />C) \(3\frac{1}{5} \cdot \frac{6}{5} = \frac{16}{5} \cdot \frac{6}{5} = \frac{96}{25} = 3.84\)<br /><br />D) \(9 \cdot \frac{1}{5} = \frac{9}{5} = 1.8\)<br /><br />The largest result is from option A, which is 20.25.
